Warner was also fined $11,500 after pleading guilty to a charge of unbecoming behaviour after throwing a punch at England's Joe Root at Birmingham's Walkabout Inn early last Sunday morning after Australia's heavy Champions Trophy loss.

He admitted he was drinking the night of the incident and was "aggressive" at the bar but insists he does not have a problem with alcohol.

"Definitely not. I don't think I've got a drinking problem at all," Warner told a packed press conference in London. "It's just basically I've got to make the right decisions at the right time."

It is the second time in three weeks that Warner has pleaded guilty to the same charge.

He was fined $5750 last month after an expletive-laden Twitter rant.

The suspension and fine caps off a miserable few months for Warner, who struggled during Australia's 4-0 series loss to India in March and was internally reprimanded for being overweight.

He also struggled in the IPL and his scores in England were two ducks in Champions Trophy practice matches and nine against England before being stood down for Wednesday's match against New Zealand.

Warner's suspension means that veteran opener Chris Rogers must now be a certainty.

Rogers, 35, a one-Test veteran, is currently leading the county run-scoring in England, playing for Middlesex.

With Warner suspended Australia will have just six batsmen to choose from heading into the Ashes.

The real reprieve may be for Ed Cowan, who is having a more modest country season with Nottingham and must have been under great pressure from Rogers to keep his place.

It also makes the return of Shane Watson to the top of the order in the Ashes more likely and ensures that Usman Khawaja will regain his place in the Test side.

WARNER'S TEST HOPES FADEYesterday, former England captain Michael Vaughan said Warner must have a "screw loose'' for punching Root a month out from an Ashes series.

Vaughan said Warner's unprovoked attack on Root had "tarnished the whole Australia cricket team'' by ensuring the storm of uncertainty surrounding their Ashes prospects turned into a tornado.

"I'm all for players relaxing and having fun. But to go and punch an opposing player unprovoked in a bar, you've got to have some kind of screw loose to do that,'' Vaughan told BBC Sport.

"I can't believe that an opposing player would want to punch one of the England players and then you find out more about the incident. It was an unprovoked attack."

Witnesses described how the Australian and English players arrived at the Walkabout Aussie-themed pub about 1.30am and were ushered together to a VIP area close to the bar.
